An older man went to his doctor with a variety of complaints. After examining him, the doctor said, "Well, you've got some problems, all right, but if you'd give up smoking, drinking, and chasing women, I think you'd last a good while longer."
"But Doc," answered the man, "I don't smoke, drink, or chase women."
"Oh," replied the doctor, "I'm sorry."
Moral: Keep some vices to give up in your old age.
